View clinical trials related to Cataract.
Filter by:Cataract surgery represents a common surgical intervention, encompassing the extraction of the opaque natural crystalline lens, followed by the substitution with an artificial intraocular lens (IOL). To ascertain an IOL possessing optimal power, antecedent to the surgery, preoperative evaluations are conducted through the utilization of a biometric devices. Diverse categories of these instruments are accessible, each harnessing distinct optical methodologies or mathematical algorithms to ascertain the most fitting IOL power. The principal objective of this study was to evaluate the ocular biometry and the predictive precision outcome of a biometer that uses standard keratometry to the prediction accuracy of another biometer that uses Total Keratometry.
Assessment of cataract development in patients with regular caffeine consumption and those without caffeine consumption after pars plana vitrectomy.
Comparison of the clinical performance of two enhanced monofocal IOLs with similar design.
The goal of this clinical trial is to compare the performance of 2 intraocular lenses (IOLs): ARTIS SYMBIOSE (study lenses) vs PANOPTIX (comparator) through binocular Distance Corrected Intermediate Visual Acuity (DCIVA) assessed at 80 cm in photopic conditions at minimum 1-month post-operative by a blinded evaluator. This main objective will be to show superiority of the ARTIS SYMBIOSE system on the primary endpoint. The patient population to be included is patient suffering from cataract who requires cataract surgery procedure that meet the inclusion and non-inclusion criteria and provide written informed consent. Participants will attend a total of 5 study visits: 1 preoperative visit, 1 surgery visit and 3 postoperative visits.
To investigate the impact of high vs low Intraocular Pressure (IOP) on the intraoperative experience for the patient and surgeon. Operating at a more physiologic IOP using Active Sentry hand piece during cataract surgery will result in significantly less discomfort/pain as assessed by the decreased need for rescue medication
The goal of this clinical trial is to compare the performance of 3 intraocular lenses (IOLs): FineVision (comparator), ARTIS SYMBIOSE (study lenses), and Tecnis Synergy (comparator) through binocular distance-corrected defocus curve. This main objective will be to show superiority of the ARTIS SYMBIOSE system through binocular distance-corrected defocus curve. The patient population to be included is patient suffering from cataract who requires cataract surgery procedure that meet the inclusion and non-inclusion criteria and provide written informed consent. Participants will attend a total of 5 study visits: 1 preoperative visit, 1 surgery visit and 3 postoperative visits.
This study is designed to explore dry eye disease (DED) pattern: ocular surface, corneal morphological changes, patients' subjective assessment of DED and their correlations with ocular surface inflammation, pain biomarkers after cataract surgery according to ocular surface lubrication with artificial tears during long-term follow-up.
To evaluate the visual and refractive outcomes after an intraocular lens (IOL) implantation in pediatric eyes with cataract and preexisting corneal astigmatism
The goal of this registry study is to optimize the results with intraocular lens implants used in cataract surgery.
The primary objective of this study is to identify how many focal points and at which distances are necessary for reliable visual curve formation and area of the curve (AoC) calculation using mathematical models and comparing the results to measurements acquired from participants that underwent uncomplicated pseudophakic presbyopia surgery.
